Gardening shears

ABSTRACT

A pair of gardening shears comprise a blade fastened to one end of a first handle, and a fixed jaw plate fastened to one end of a second handle which is pivotally fastened with the first handle by a pivoting member. The pivoting member is formed of a pivot and a nut which is engaged with the pivot and is located by a locating plate. The nut is provided with a toothed portion. The locating plate is provided with a toothed portion which is engaged with the toothed portion of the nut. The fixed jaw plate is provided with a recessed edge which is opposite in location to the blade and is intended to reduce friction between the fixed jaw plate and the blade.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to a pair of gardeningshears, and more particularly to a pair of gardening shears which areprovided with means to prevent the deposit of twigs between a movableblade and a fixed jaw plate of the gardening shears, and means to fixsecurely a pivoting joint so as to bring about effectively the scissorsaction of the gardening shears.

[0003] 2. Description of Related Art

[0004] As shown in FIG. 1, a pair of gardening shears of the prior artcomprise a first handle 11, a second handle 13, a movable blade 10fastened at one end of the first handle 11, a fixed jaw 12 fastened atone end of the second handle 13, and a pivot 14 for fastening pivotallythe movable blade 10 and the fixed jaw 12 in conjunction with a nut 15and a pad 16. A locating knob 17 is pivoted to the first handle 11 andis provided with a stop edge 18. The nut 15 is provided with a toothedperiphery 20 for engaging the teeth 21 of a toothed piece 19, so as tofix the nut 15. The fixed jaw 12 has a smooth planar side 22 opposite inlocation to the movable blade 10.

[0005] The gardening shears of the prior art described above aredefective in design in that the toothed piece 19 is made by a specialmolding tool at an additional production cost, and that the toothedpiece 19 is not effective in locating the nut 15. In addition, thelocating knob 17 is not strong enough to withstand the pressure for aprolonged period of time, thereby undermining the service life span ofthe prior art gardening shears. In light of the friction between theplanar side 22 of the fixed jaw 12 and the movable blade 10, the twigsare apt to deposit between the blade 10 and the planar side 22 of thefixed jaw 12, thereby resulting in the jamming of the blade 10 and thefixed jaw 12.

BRIEF SUMMARY OF THE INVENTION

[0006] The primary objective of the present invention is to provide apair of gardening shears which are free of the shortcomings of the priorart gardening shears described above.

[0007] The foregoing objective of the present invention is achieved bythe gardening shears comprising a blade and a fixed jaw plate fastenedpivotally with the blade by a pivot in conjunction with a nut and alocating plate for locating the nut. The fixed jaw plate is providedwith a recessed edge serving to abate friction between the blade and thefixed jaw plate.

[0008] The features and the functions of the present invention will bemore readily understood upon a thoughtful deliberation of the followingdetailed description of a preferred embodiment of the present inventionwith reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0015] As shown in FIGS. 2-6, a pair of gardening shears of thepreferred embodiment of the present invention comprise a blade 30fastened at one end of a first handle 31, a fixed jaw plate 32 fastenedat one end of a second handle 33, and a pivoting member formed of apivot 34, a nut 35 and a locating plate 40.

[0016] The blade 30 is provided with a threaded hole 38 and a locatingknob 37 which is fastened along with the blade 30 to the first handle 31by a fastening bolt 39 that is engaged with the threaded hole 38.

[0017] The fixed jaw plate 32 is provided with a locating hole 43 and afastening hole 46. The fixed jaw plate 32 is fastened along with thepivoting member to the second handle 33 such that the fixed jaw plate 32is fastened pivotally with the blade 30 by the pivot 34 which is engagedwith the nut 35 via the locating plate 40. The locating plate 40 isfastened with the fixed jaw plate 32 and the second handle 33 by afastening bolt 45 which is engaged with a fastening hole 46 of thesecond handle 33 via a fastening hole 46 of the fixed jaw plate 32 and athrough hole 44 of the locating plate 40. The locating plate 40 isprovided in the inner side with a locating projection 42 which isreceived in a locating hole 43 of the fixed jaw plate 32. The locatingplate 40 is provided in the outer side with a toothed portion 41. Thenut 35 is provided in the inner side with a toothed portion 36 which isengaged with the toothed portion 41 of the locating plate 40. As aresult, the nut 35 is securely located by the locating plate.

[0018] The fixed jaw plate 32 is provided with a recessed edge 51 whichis opposite in location to the blade 30 for abating friction between thefixed jaw plate 32 and the blade 30, so as to prolong the service lifespan of the blade 30.

[0019] The preferred embodiment of the present invention described aboveis to be regarded in all respects as being merely illustrative and notrestrictive. Accordingly, the present invention may be embodied in otherspecific forms without deviating from the spirit thereof. The presentinvention is therefore to be limited only by the scopes of the followingclaims.
